Kubernetes 儀表板無法運作，“已存在”和“找不到要求的資源（獲取服務堆）”

我是 Kubernetes 新手

目標是讓 Kubernetes 叢集儀表板正常運作

當我kubectl create -f https://raw.githubusercontent.com/kubernetes/dashboard/master/src/deploy/recommended/kubernetes-dashboard.yaml --validate=false按照描述做時這裡

我得到：

Error from server (AlreadyExists): error when creating "https://raw.githubusercontent.com/kubernetes/dashboard/master/src/deploy/recommended/kubernetes-dashboard.yaml": secrets "kubernetes-dashboard-certs" already exists
Error from server (AlreadyExists): error when creating "https://raw.githubusercontent.com/kubernetes/dashboard/master/src/deploy/recommended/kubernetes-dashboard.yaml": serviceaccounts "kubernetes-dashboard" already exists
Error from server (AlreadyExists): error when creating "https://raw.githubusercontent.com/kubernetes/dashboard/master/src/deploy/recommended/kubernetes-dashboard.yaml": roles.rbac.authorization.k8s.io "kubernetes-dashboard-minimal" already exists

Error from server (AlreadyExists): error when creating "https://raw.githubusercontent.com/kubernetes/dashboard/master/src/deploy/recommended/kubernetes-dashboard.yaml": services "kubernetes-dashboard" already exists

當我跑步時kubectl get services --namespace kube-system，我得到：

NAME                   CLUSTER-IP      EXTERNAL-IP   PORT(S)         AGE
kube-dns               10.233.0.3      <none>        53/UDP,53/TCP   10d
kubernetes-dashboard   10.233.28.132   <none>        80/TCP          9d

當我嘗試存取儀表板 kubernetes 叢集時，我得到Connection refused

kubectl logs --namespace=kube-system kubernetes-dashboard-4167803980-1dz53輸出：

如何讓儀表板正常運作？感謝你的幫助。

答案1

首先刪除所有內容：

kubectl delete -f https://raw.githubusercontent.com/kubernetes/dashboard/master/src/deploy/recommended/kubernetes-dashboard.yaml

然後重新建立儀表板：

kubectl create -f https://raw.githubusercontent.com/kubernetes/dashboard/master/src/deploy/recommended/kubernetes-dashboard.yaml

啟動代理：

kubectl proxy

然後打開它：

http://localhost:8001/api/v1/namespaces/kube-system/services/https:kubernetes-dashboard:/proxy/

您也可以使用 k8s api 位址而不是 localhost。請注意，在某些新的儀表板版本中，ui例如：的短地址k8s.api.example.com/ui不再有效，您需要明確使用長而難看的地址。
